HTTP Authentication

HTTP supports the use of several authentication mechanisms to control
access to pages and other resources. These mechanisms are all based
around the use of the 401 status code and the WWW-Authenticate
response header. The client sends the username and password as
unencrypted, base64-encoded text. Because it is unencrypted, it should
only be used with HTTPS, as the password can be easily captured and
reused over HTTP.
Luckily, LingoHub encrypts all communication with SSL.
